Hi Terry I think off the top of my head that if you specify the categories in the "scat" query string parameter separated by commas that should work. For instance...
scat=3,7,46
Can you try that and let me know if it works for you?
Hi Terry I just tried here to double check and printed out the categories searched and all of them were. Are you adding the "pg=1" to the querystring to initiate the search?
